Discovery of four gravitational lensing systems by clusters in the SDSS DR6
We report the discovery of 4 strong gravitational lensing systems by visual
inspections of the Sloan Digital Sky Survey images of galaxy clusters in Data
Release 6 (SDSS DR6). Two of the four systems show Einstein rings while the
others show tangential giant arcs. These arcs or rings have large angular
separations (>8") from the bright central galaxies and show bluer color
compared with the red cluster galaxies. In addition, we found 5 probable and 4
possible lenses by galaxy clusters.Comment: 6 pages, 3 figures. Added referenc

Characteristics of a 4-fold segmented clover detectore
Four high-purity germanium 4-fold segmented Clover detectors have been applied in the experiment of neutron-rich nucleus N-21. The performance of those, four Clovers have been tested with radioactive sources and in-beam experiments and the main results including energy resolution, peak-to-total ratios, the variation of the hit pattern distribution in difficult crystals of one Clover detector with the energy of gamma ray, and absolute full energy peak detection efficiency curve, were presented.National Basic Research Program (973 program) of China 2007CB81500
